What are some common use cases for using Underscore.js in a project?

Common use cases for using Underscore.js in a project are data manipulation, iterating over collections, object cloning and merging, sorting and finding data, and event handling. Underscore.js simplifies data manipulation with following functions: _.map, _.filter, and _.reduce. These functions help transform or filter arrays and objects in a concise manner. For iterating over collections, functions like _.each make loops more readable compared to traditional for loops.
Object cloning and merging are made easier with functions: _.clone and _.extend, useful for managing complex state. Sorting and searching are streamlined with these utilities: _.sortBy and _.findWhere, especially when working with arrays of objects. Finally, _.debounce and _.throttle help in controlling the frequency of the execution of a function, whether it’s scrolling or resizing .
